IMPROVEMENT IN CLQVER-SEPARATQR-S.

Specification forming part of Letters Patent No. 150,210, dated April28, 1874; application filed June 18, 1873.

To all whom it may concern:

Be it known that 1, DAVID WVHITING, of Ashland, in the county of Ashlandand State of Ohio, have invented certain new and useful Improvements inGlover-Separators and that the following is a full, clear, and exactspecification thereof, which will enable others skilled in the art tomake and use the said invention.

My invention relates to certain improvements in clover-separators, andparticularly to the separating, discharging, and blast ap paratusconnected therewith. Said invention consists in the combination, withthe slatted separating-apron, of a slatted separating-platform made intwo sections, one of which can be slid endwise along the other, so that,when the separating-apron is stretched, the separating-platform mayretain its relative position with reference to the apron withouteffecting the continuity of the platform, as is hereinafter more fullyshown. Said invention also consists in the combination of the slidingsection of the slatted separating-platform with the stretching device ofthe separating-apron by means of connecting-links, as is hereinaftermore fully shown, whereby the use of a separate device for operating thesliding section of the platform is made unnecessary, and the adjustmentof both the apron and platform is effected at one operation. Saidinvention also consists in the combination, with the fan-case, of apeculiarly-constructed blast-regulator, by means of which the seedsfalling through the sieves to the discharge-spout may be subjected totwo distinct blasts, as is hereinafter more fully shown.

In the accompanying drawing, Figure 1 is a plan of a part of aseparating apron and platform with the tightening and regulating device,a piece of the frame being broken oif to show said device. Fig. 2 is aside view of said tightening device for the apron and platform. Fig. 3is a plan of a part of the separating-sieves, the tailing-spout, andblast-regulator, with the separating apron and platform removed. Figs.4. are side and end views of separating-platform with its end curvedplate. Fig. 5 is a section through the line a: m, Fig. 1, with that partof the frame over the fan and cylinder shown in position.

A are the longitudinal slats, which compose the separating-platform, andwhich are divided between the rods to a that support the adjacent ends,so as to make tWO sections, one of which, a, is stationary, while theother section a. has a slight longitudinal motion'on the crossrods B anda that work in slots in the frame pieces R, the inner ends of the slatsof section a sliding alongside of the ends of the slats of section a, asshown in Fig. 1, between the rods to and a. The rod B is secured to thelongitudinal slats A of the separating-apron a, and is made to slide ina slot, T, Fig. 2, by means of connecting-links G that connect the endsof the said rod with the tightening device E F f at the shaft D, whichdevice is of the same general construction as that shown in LettersPatent 103,806, granted to me May 31, A. D. 1870, for improvements inclovermachines. H is an inwardly-concave plate,

secured to the outer and curved ends of the movable section of theseparating-platform, and so arranged that, through the action of thetightening device on the movable section of the separating-platform, itis kept flush with the outer slats of the separating-apron. 1, 2, and 3are the sections of the upper sieve, and 4 is the lower sieve, the wholemaking the grain-separating shoe. Q is the grain-shoe,

end by the swinging arms P, and hanging and swinging at its inner end onthe arms 1?, which are not fastened to the grain-separating shoe, thesaid arrangement of the arms P P, with reference to the grain-shoe Q andgrain-separating shoe 1,2,3, and 4, giving the grain-shoe Q the samelongitudinal motion as that given to the grain-separating shoe by thecrank-shaft L without the tilting motion given to the inner end of saidseparating-shoe. J is the tailingspout, made with asharply-inclinedbottom, and securely fastened to the grain-shoe Q, sothat the longitudinal swinging motion given to the grain-shoe andgrain-separating shoe is also given to the tailing-spout. S S are theseparating-bars, secured to the outer end of the grain-separatin g shoe,so as to project over the tailing-spout J. I is the blast-regulator of atriangular cross-section, having its broad face adjacent to the floor ofthe frame, and is secured at its inner end to a rod, V, journaled to theside pieces of the frame in such a posiwasted.

tion as to bring the inner edge of said regulator above the door, theregulator being raised at its outer end to admit a blast by a rod orpins, W, sliding in slots in the frame. Said regulator is located at theexit-port of the fancase, and is arranged so that its inner and uppersloping face will receive the grain falling from the sieves 3 and 4t andthe grain-shoe Q, and turn it into the discharge-spout K, while over itsouter faceY a blast is being given to the grain falling through thesieves, and at the same time, if desired, from under its lower face asecond blast can be given to the grain as it falls from the inner andupper face of said regulator into the discharge-spout, this second blastcoming out under the grain-shoe.

These several improvements operate as follows: Heretofore when theseparating-apron M N has been tightened by the tightening devie E F f,the se 'iarating-platform A A has remained stationary, and'the outer endthereof was rendered in great part useless on account of its not keepingthe same relative position with reference to the slats of the apronabove, but leaving a considerable space between it and the outerapron-slats, through which the stemmed heads have fallen and been Toremedy this I make the separatin g platform in two sections, and secureto the outer ends of the slats of the movable section theinwardly-concave plate H, which catches all the heads and turns theminto the shoe below, the movable section B a of the separating-platformbeing connected to the aprontightening device by the bars C G. hen theoperator tightens the apron by working the screws E, he also regulatesthe movable section of the separating-platform, and keeps it in the samerelative position with reference to the apron above, the bars 0 causingthe bar 13, to which the movable section of said platform is secured, tomove forward or backward in the slots in the frame It It, according asthe box at D is moved. The tailing-spout J is here shown as beingconnected to the grainshoe Q, but, if preferred, it could be connectedto the grain-separating shoe, as the essential feature is to have ithave the longitudinal shaking motion of the grain separating shoe andgrain-shoe, in order to insure the passage of the tailings down thespout.

When there is not much dust in the heads of grain, and only an ordin ar1 blast is required, the blast'regulator I is left in the position notedby the dotted lines; but when said blast is not sufficient to thoroughlyseparate the finer chaff anddust from the grain, the endY of theblast-regulator is raised when a blast of air, created by the fan (theposition of which is shown by the dotted lines, Fi 5) rushes through thepassage formed under said regulator onto the seeds and chaff fallingfrom the upper and inner face of said regulator into the discharge-spoutK, thereby blowing away the dust and fine chaff that may have escapedthe blast above.

hat I claim as new, and desire to secure by Letters Patent, is-

1. A slatted separatin g-platform, constructed in two sections, onemovable and the other stationary, substantially as and for the purposedescribed.

2. The combination, with a slatted separating-apron and tighteningdevice, of a slatted separating-platform constructed in two sections,and connecting-bars O C, whereby the tightening of the apron andadjustment of the two-part slatted platform are simultaneously eflfectedby one tightening device, substantially as and for the purposespecified.

3. The combination, with a slatted separatingplatform, having curvedouter ends of an inwardly-curved plate, H, substantially as and for thepurpose specified.

.4. The blast-regulator I, of triangular form, arranged to receive thefalling grain from grain-shoe Q, and serving as the means of directin gone or two blasts of air onto the grain between its entrance into thesieves and its passage to the discharge-spout, substantially as and forthe purpose specified.
